Spreader Penetration During Lateral Compaction of Resilon and Gutta-Percha

Fracture resistance of roots filled with gutta-percha or RealSeal®

“…This difference means that RealSeal Ò can flow more easily and will distribute stress more efficiently than gutta-percha. This explanation corresponds to the finding of Nielsen & Baumgartner (2006) that ResilonÔ allowed deeper spreader penetration into the root filling than gutta-percha with the same controlled pressure. Williams et al (2006) also reported lower cohesive strength and stiffness of ResilonÔ than gutta-percha under tensile loading, but did not consider the differences to be clinically relevant.…”

Comparison of Apical Leakage between Canals Filled with Gutta-Percha/AH-Plus and the Resilon/Epiphany System, When Submitted to Two Filling Techniques

“…The other groups showed some spaces, but they were extremely small when compared with this group. With respect to use of the LC technique, Resilon presented greater penetration depth of the nickel-titanium digital spreader than the gutta-percha, providing better sealing (28). Leakage presented by RES was confined to the apical third with mean leakage values of 2.09 mm for LC and 1.91 mm for HT.…”

Scanning electron microscopic evaluation of dentinal tubule penetration of Epiphany in severely curved root canals

“…[7,9] Resilon has also been shown to increase the depth of sealer penetration during lateral compaction in comparison with gutta-percha. [10] Sealer penetration into dentinal tubules is considered to be potentially beneficial because it increases the interface between the core material and dentinal walls, which may improve the mechanical retention of the material via sealer plug interlocking inside the tubules. [11] Furthermore, the sealer's antibacterial activity effectively eliminates bacteria and those remaining inside dentinal tubules are entombed.…”
